Hi,

Today I received this message on my serial console:

in_cksum_skip: out of data by 260
Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 00
fault virtual address   = 0xc

Uptime: 1d15h8m10s

This server has been very stable for a very long time. This crash surprises
me somewhat.
Uname output:
FreeBSD carnen.net 5.3-STABLE FreeBSD 5.3-STABLE #0: Wed Feb  2 21:02:44 CET
2005     root@carnen.net:/usr/obj/usr/src/sys/CARNEN  i386

Any idea what could have caused this?

Thanks,
/Eirik
